Added wikipedia "about" feature

[nedved2357]

I've added the feature to click a node on the graph and get Wikipedia information about it displayed on the side.

Two notes:

1. If there doesn't exist a wiki page with this name (as of the label) an error message is displayed.
2. My CSS and design skills are terrible, I would say I haven't much of a clue about how to go around with layouts, so this initial layout is very basic, and hopefully I'll get around making it pretty :)
